Why This Category Exists
Your API may depend on third-party APIs for identity, payments, enrichment, or workflows. Blind trust in external responses, schemas, and availability can cascade failures and security incidents into your platform.
Common Impact
- Data integrity issues from untrusted third-party responses.
- Security bypass through malformed or malicious upstream data.
- Service disruption when dependent APIs fail or degrade.
Prevention Checklist
- Validate and sanitize all inbound data from partner APIs.
- Use timeouts, retries, circuit breakers, and fallback behavior.
- Apply least-privilege credentials and network segmentation.
- Continuously assess third-party API security and change risk.
